Question

Lindsey and Eduardo are waiting for an elevator on the ground floor. First, Lindsey boards an elevator and starts going up at a rate of 130 meters per minute. A few moments later, when Lindsey's elevator has traveled 190 meters, Eduardo boards an express elevator and starts going up at a rate of 240 meters per minute. In how long will Eduardo pass Lindsey?​

Answer 1

See below

Explanation:

Lindsey height = 190 + 130 m ( m = minutes)

Eduardo height = 240 m

Equate them

190 + 130 m = 240 m

190 = 110 m

190/ 110 = 1 8/11 minutes after Eduardo starts
