hey mate ... here is ur answer ....
2 hours 30 minutes .
Step-by-step explanation:
It takes 90 min to travel 60 Km .
Therefore, 60km-90min
100km= ?
= 100*90/60
=150min
therefore ans = 2hour 30min
hope this will help uh ....
have a great day ahead ...
Answer:
2 hr 30 min
Step-by-step explanation:
You travel 60km per 90 minutes which is equivalent to 60km90min
This is by definition a rate (r=d/t). We want to know how long (time) it will take to travel 100km
So we are looking for 100kmt . Because the rates are the same, the two expressions are equal and thus can be set equal.
60km90min=100kmt
Cross multiply the denominator of t and 90min to the opposite sides.
60km⋅t=100km⋅90min
Finish solving for t
Divide by 60km on both sides.
t=100km⋅90min60km
Now simplify.
The km over km will cancel and we will be left with units of time in minutes. I will do the multiplication at this time as well.
t=900min60
Again, simplify by doing the division to arrive at
t=150min
