Question

the ratio of speed of Manu Tanu and Tanu 3:4:7 how much time will it take to cover a distance that Tanu takes 30 minut to cover​

Answer 1

If the ratio of speed of Manu Tanu and Tanu 3:4:7 then

then the speed of Manu Tanu and Tanu = 3 x 4 x and 7x respectively.

if 4x = 30 minutes

then then x = 30/4 min

therefore, the speed of Manu Tanu and Tanu = 3×30/4, 4 × 30/3 and 7 × 30/4 respectively

hence,, the speed of Manu Tanu and Tanu = 90/4 min, 120/4 and 210/4 minutes respectively.
