Question

3. A car takes 10 hours to reach a destination by travelling at the speed of 65 km/hr. How long will it take when the car travels at the speed of 50 km/hr.
4. If 45 persons can consume a stock of food in 2 months, find how many days the same
stock of food will last for 27 persons?

Answer 1

Step-by-step explanation:

3.Speed of the car=65 km/h

Time=10 hours

So total distance-time-speed

=10×65-650 km

If the speed=50 km/h

then time=distance/speed

=650/50-13 hours (Answer)

4.For 45 students it is for 60 days. So for 1 student it is for 60 x 45 days. So for 27 students it will be for (60x45)/27 = 100 days.
