Juan Pablo demora 7 minutos en dar una vuelta a la cancha de fútbol y Pedro demora 2 minutos más corriendo a la misma velocidad que Juan Pablo. ¿Cuánto tiempo demorará Pedro en dar 12 vueltas?

108 minutes

Step-by-step explanation:

This translates to:

Juan Pablo takes 7 minutes to do a full lap on a football field, Pedro needs 2 more minutes ruuning at the same speed thanJuan Pablo.

How much time does Pedro need to do 12 laps?

The fact that Pedro runs at the same speed than Juan Pablo, and needs more time, may mean that the radius of the laps of Pedro are a little bit bigger than the ones of Juan Pablo (which means that the total distance that pedro runs is bigger)

If Juan Pablo does a lap in 7 minutes, then Pedro does a lap in 7 minutes + 2 minutes = 9 minutes.

Then to do 12 laps, he needs 12 times that amount of time, this is:

12*9 min = 108 minutes

b. x- 48 =120

step-by-step explanation:

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
