Car moving at an average speed of 56 whole 3.5 kilometre per hour how ...
Calculating the distance covered:
To calculate the distance covered by the car, we need to use the formula:
Distance = Speed × Time
Given that the car is moving at an average speed of 56 3.5 km/h and the time is 7 1/2 hours, we can substitute these values into the formula to find the distance covered.
Converting the speed:
First, let's convert the average speed from 56 3.5 km/h to a decimal form. To do this, we need to add the whole number part (56) and the fractional part (3.5) together:
56 + 3.5 = 59.5 km/h
So, the car is moving at an average speed of 59.5 km/h.
Converting the time:
Next, let's convert the time from 7 1/2 hours to a decimal form. To do this, we can convert the mixed number into an improper fraction:
7 1/2 = 7 + 1/2 = 14/2 + 1/2 = 15/2
Therefore, the time is 15/2 hours.
Calculating the distance:
Now that we have the speed (59.5 km/h) and the time (15/2 hours), we can substitute these values into the distance formula:
Distance = Speed × Time
Distance = 59.5 km/h × 15/2 hours
To simplify this calculation, we can cancel out the units:
Distance = (59.5 × 15) km
Distance = 892.5 km
Therefore, the car will cover a distance of 892.5 kilometers in 7 1/2 hours.
Summary:
- The car is moving at an average speed of 56 3.5 km/h, which is equivalent to 59.5 km/h.
- The time taken by the car is 7 1/2 hours, which is equivalent to 15/2 hours.
- Using the distance formula, Distance = Speed × Time, we can calculate the distance covered.
- Substituting the values, Distance = 59.5 km/h × 15/2 hours.
- Simplifying the calculation, we find that the car will cover a distance of 892.5 kilometers.
- Therefore, in 7 1/2 hours, the car will cover a distance of 892.5 kilometers.

Given :
Average speed of car = 56 3/5 km per hour
Which is equal to 283/5 km per hour, when converted to improper fraction.
Now, time that is available = 7 1/2 hours, which is 15/2 hours, in improper fraction.
So, total distance that will be covered = 283/5 * 15/2 =(283*2)/2
= 849/2
= 424.5
Therefore, the distance covered by the car = 424.5 km.
