Question

if a train covers 120 km in 3 hours how much time would it take to cover 150 km at the same rate

Answer 1

hi
let the time taken be x
as, they are in direct proportion
so,
120/3=150/x
40=150/x
x=150/40
 x=3.75
therefore time taken=4hrs 15 min







hope it helps☺☺

Answer 2

Here is your answer
----------------------------------------------------------------------------------------------------------------


Let the number be x


=> 120 is to 3 as 150 is to x

=> 120 / 3 = 150 / x

=> divide the product of the means 3 * 150 = 450 to the 120x.

=> 450/120x = 3.75
