The average speed with which the vehicle travels is equal to 56 Km/hr.
Velocity is measured as a vector quantity. There is a magnitude to it as well as a direction. The magnitude of velocity is measured by speed. The S.I. unit for this is the meter per second. Additionally, there are other units like km/h and km/s. Its dimensional equation is [LT-1].
The average speed of any vehicle is calculated over a given range of time. It is the total distance traveled by the vehicle in the given interval of time divided by the given time interval. It is a scaler quantity.
Average speed= Total Distance/ Time Taken
Given in the question
Distance = 140 km
Time of leaving Leeds = 8.00 am
Time of arriving Newcastle = 10.30 am
Time Taken = Time of arriving Newcastle - Time of leaving Leeds
= 10.30 - 8.00
= 2 hours and 30 minutes
So, the time taken is = 2.5 hr
Put in the values, we get
Average speed= Total Distance/ Time Taken
Average speed= 140/ 2.5 Km/Hr
Average speed= 56 Km/Hr
So, the average speed with which the vehicle travels is equal to 56 Km/hr.
