Question

Dave starts walking at a speed of 5 km/hr through half the distance, rest of the distance dave covers with a speed 4km/hr. Total time of travel is 9 hours. What is the maximum distance dave can cover?

Answer 1

Answer:

40 Km

Step-by-step explanation:

From the photo We get that

y=4h

thus the maximum distance covered will be - 5=x/2(y)

or. 5=x/2(4)

or. 5=x/8

or. 40=x

Maximum distance covered= 40Km
