The time it takes to travel to a destination varies inversely with the average speed. It takes two hours when the average speed is 40mph.
If the average speed changes to 80mph, what is the new travel time?

Answer:

1 hour

Step-by-step explanation:

The time it takes to travel to a destination varies inversely as its speed

T= k/S

K= TS

Time= 2 hours

Speed= 40mph

K= 2×40

= 80

Therefore if the average speed changes to 80mph then the new travel time can be calculated as follows

T= 80/80

= 1 hour

Hence the new travel time is 1 hour
