Question

In how many min I will finish a 2hr 40min video if i'm watching at 1.75x speed?

Answer 1

7.5 minutes.

This speed is faster in a quarter (1/4) than the regular speed.

Because if you watch it in x2 speed, means you divide the time by two, but you watch in a x1.5 speed, means a half of x2 speed.

Thus, if the time is 10 minutes, and the speed is a 1.5 speed, the time is divided by 1/4:

10 - 10/4 = 7.5 minutes.
