Time & Distance Mcqs

Q.  Two automobiles are 150 kilometers apart and traveling toward each other. One automobile is moving at 60km/h and the other is moving at 40km/h mph. In how many hours will they meet?

a. 2.5
b. 2.0
c. 1.75
d. 1.5
e. 1.25


ANSWER: See Answer
 
One moves at 60km/h, so in an hour, he’ll travel 60km
The other moves at 40km/h, so in an hour, he’ll travel 40km
This is towards each other, so, in an hour, we can say that they’ll get 60+40=100km closer.

This means that they get closer at 100km/h

Given that we have the distance of 150km, and the speed of closure at 100kmh, we can now use the equation

S=D/T

Rearrange to find T (times both sides by T)

S x T = D (now divide both sides by S)

T=D/S

Time = 150km divided by 100km/h

Time = 1.5 hours

Or one hour and 30 minutes
