Question

A car and bike started from point A at a speed of 45 kmph and 70 kmph respectively in same direction. Calculate distance between the car and bike after 4 hours.
1. 90 km
2. 100 km
3. 120 km
4. 140 km

Answer 1

Correct Answer - Option 2 : 100 km

Given:

Speed of car = 45 kmph

Speed of bike = 70 kmph

Formula used:

Speed = Distance/ Time

m/ s = 5/ 18 km/hr

Calculation:

Distance travelled by car = 45 × 4

⇒ Distance travelled by car = 180 km

Distance travelled by bike = 70 × 4

⇒ distance travelled by bike = 280 km

Difference = 280 – 180

∴ Difference between both the vehicles after 4 hours is 100 km
