A pizza boy after travelling 75km meets with a travelling jam and then...
Given Information:
- The pizza boy travels a distance of 75 km.
- He encounters a traffic jam and then proceeds at 3/4 of his former speed.
- He arrives at his destination 45 minutes late.
- If the traffic jam had occurred 48 km further, he would have arrived 25 minutes late.
Let's assume:
- The normal speed of the pizza boy is 'x' km/hr.
- The time taken to travel the initial 75 km without the traffic jam is 't' hours.
- The reduced speed after encountering the traffic jam is (3/4)x km/hr.
Calculating Time and Speed:
- Time taken to travel the initial 75 km without the traffic jam = t hours.
- Time taken to travel the remaining distance after encountering the traffic jam = (75 - 48)/(3/4)x = 100/x hours.
- Total time taken to reach the destination = t + 100/x hours.
Equations:
- Equation 1: t + 100/x = t + 45/60 (45 minutes = 45/60 hours)
- Equation 2: t + 100/x = t + 25/60 (25 minutes = 25/60 hours)
Solving the Equations:
- Equation 1: t + 100/x = t + 45/60
=> 100/x = 45/60
=> x = 100 * 60 / 45
=> x = 80 km/hr
- Equation 2: t + 100/x = t + 25/60
=> 100/x = 25/60
=> x = 100 * 60 / 25
=> x = 240 km/hr
Final Answer:
The normal speed of the pizza boy is 80 km/hr.
- The pizza boy travels a distance of 75 km.
- He encounters a traffic jam and then proceeds at 3/4 of his former speed.
- He arrives at his destination 45 minutes late.
- If the traffic jam had occurred 48 km further, he would have arrived 25 minutes late.
Let's assume:
- The normal speed of the pizza boy is 'x' km/hr.
- The time taken to travel the initial 75 km without the traffic jam is 't' hours.
- The reduced speed after encountering the traffic jam is (3/4)x km/hr.
Calculating Time and Speed:
- Time taken to travel the initial 75 km without the traffic jam = t hours.
- Time taken to travel the remaining distance after encountering the traffic jam = (75 - 48)/(3/4)x = 100/x hours.
- Total time taken to reach the destination = t + 100/x hours.
Equations:
- Equation 1: t + 100/x = t + 45/60 (45 minutes = 45/60 hours)
- Equation 2: t + 100/x = t + 25/60 (25 minutes = 25/60 hours)
Solving the Equations:
- Equation 1: t + 100/x = t + 45/60
=> 100/x = 45/60
=> x = 100 * 60 / 45
=> x = 80 km/hr
- Equation 2: t + 100/x = t + 25/60
=> 100/x = 25/60
=> x = 100 * 60 / 25
=> x = 240 km/hr
Final Answer:
The normal speed of the pizza boy is 80 km/hr.
