**Quantitative Aptitude – Arithmetic – Time Speed and Distance**

**Question**

A motorbike leaves point A at 1 pm and moves towards point B at a uniform speed. A car leaves point B at 2 pm and moves towards point A at a uniform speed which is double that of the motorbike. They meet at 3:40 pm at a point which is 168 km away from A. What is the distance, in km, between A and B?

A) 364

B) 378

C) 380

D) 388

**Answer**

Option (B)

**Solution**

From CAT 2017 – Quantitative Aptitude – Arithmetic – Time Speed and Distance, we can see that,

Speed of motorbike = s

Speed of car = 2s

Distance covered by motorbike in 1 hr = s km

Motorbike takes 2hrs 40 mins to reach the point where both car and motorbike meet.

In 2 hrs 40 mins, motorbike will cover a distance of 8s/3 = 168. So, s = 63

Since, speed of car is double than motorbike. So,

Distance covered by car in 1 hr 40 mins = 2 * Distance covered by motorbike in 1 hr 40 mins

Distance covered by motorbike in 1 hr 40 mins = 105 km

Distance covered by car in 1 hr 40 mins = 210 km

So, total distance = 168 + 210 = 378 km
