# How Much Time Taken by the Truck to Travel? If

A truck travels 90 km/hr for the first 3/2 hours. After that it travels 70 km/hr. Find the time taken by the truck to travel 310 km.

- 2.5 hrs
- 3 hrs
- 3.5 hrs
- 4 hrs

**Answer: (1) 2.5 hrs.**

**Explanation:-**

Speed of a truck = 90 km/h

Distance cover by a truck in 3/2 h = 90 x 3/2

= 45 x 3 = 135 kms

Total distance = 310 km

Remaining distance = 310 – 135 = 175 km

Time taken by a truck which is speed 70 mk/h = 175/70

= 2.5 hrs.

Hence, the answer is (1) 2.5 hrs.
