Question

What is the speed of each vehicle? (Remember S=d/t)

A: 50 km/h, B: 40 km/h

A:5 km/h, B: 2 km/h

A: 10 km/h, B: 5 km/h

A: 20 km/h, B: 10 km/h

Answer 1

Answer : The correct option is A: 20 km/h, B: 10 km/h

Explanation :

Speed : It is defined as the distance traveled per unit time.

Formula used:

`S=(d)/(t)`

where,

S = speed

d = distance

t = time

First we have to calculate the speed of vehicle A.

Given:

Distance of vehicle A = 50 km

Time of vehicle A = 2.5 hr

Now putting all the given values in the above formula, we get:

`S=(50km)/(2.5hr)=20km/hr`

Now we have to calculate the speed of vehicle B.

Given:

Distance of vehicle B = 50 km

Time of vehicle B = 5 hr

Now putting all the given values in the above formula, we get:

`S=(50km)/(5hr)=10km/hr`

Therefore, the speed of vehicle A and B is 20 km/hr and 10 km/hr respectively.
