Question

Carl the rideshare driver drove 55 miles per hour per hour the first party of the trip. he was behind schedule, so he drove 70 miles per hour the second part of the trip. the trip was a total of 30 miles.
x = the time of the first part of the trip
t = the time of the second part of the trip
Write an equation in standard form that represents the situation.
(the photo is example)

Answer 1

The standard form linear equation which represents the situation is; 55x + 70t = 30

Standard linear equation

• Carl, the rideshare driver drove 55 miles per hour the first part of the trip and x = the time of the first part of the trip.

Therefore, we have; 55x.

• He drove 70 miles per hour the second party of the trip and t = the time of the second part of the trip.
• Therefore, we have; 70t.

Since, to tal distance = 30.

• We have; 55x + 70t = 30
