Calculate time required to deliver the pizza once it is ready.
 


Find the time taken by the scooter to cover 6.5 km and van to cover 4 km. Add to them the respective time of cooking.
 


Yeah, but how?
 


Imagine you are riding on the bike at 10 mph. You are 5 miles from home. How long will it take to get home?

You have the correct answer, first is faster, but I think the times you calculated are wrong
 


Stratosphere: nobody asked you to do ViralRiver homework.
 


I did T=r/d to calculate the time it takes for the moped to get to the house.

Got confused there, thought Stratosphere had asked the question originally. ViralRiver already gave the relevant equation (s=d/t) you ( or ViralRiver really) need to rearrange that for t.

This is what I got:

Ludo - 0.47 hours (2dp)
Moonlight - 0.6 hours

Is this right?
