Question

Vishal and Ethan start moving towards each other at the same time. The initial distance between them is 40 km.

Given that Vishal is cycling at a constant speed of 18 km / h and Ethan is walking at a constant speed of 8 km / h, draw a distance-time graph to illustrate this information.

Use your graph to find how long it will take for them to pass each other?

Answer 1

Answer:

time-4hour

Step-by-step explanation:

initial distance is equal to 40 kilometre

speed of Vishal cyclone is 18 kilometre per hour

speed of Ethan walking is 8 kilometre per hour

relative speed is equal to 18 - 8 is equal to 10 kilometre per hour

according to question

relative speed equal to 10 kilometre per hour

initial distance is equal to 40 kilometre

time is equal to distance upon speed

time is equal to 40 by 10

is equal to 4 hours.
