Answer 1

Correct question :

Q: A car is moving at an average speed of 40⅔ km/hour. How much distance will it cover in 7½ hours ?

Solution :-

Given : Speed = 40⅔ km/hr = 122/3 km/hr

Time = 7½ hrs = 15/2 hrs

We know that,

Distance = Time × Speed

= 122/3 km/hr × 15/2 hr

= (122 × 15)/(3 × 2) km

= 305 km

Hence,

Distance covered by a car in 7½ hours = 305 km

Answer 2

Answer:

Step-by-step explanation:

Given :-

Speed of a car = 40⅔ km/hr = 122/3 km/hr

Time taken by car = 7½ hrs = 15/2 hrs

To Find :-

Distance traveled.

Formula to be used :-

Distance = Time × Speed

Solution :-

Distance = Time × Speed

= 122/3 km/hr × 15/2 hr

= (122 × 15)/(3 × 2) km

= 305 km

Hence, The distance traveled by a car in 7½ hours is 305 km.
