The required equation is 20 + 2m = 15 + 4m. The number of miles for which Uber and Lyft would charge the same amount for the ride is 2.5 miles.
Uber charges a flat rate of $20 plus $2 per mile. Lyft charges a flat rate of $15 plus $4 per mile. We need to find out the equation and the number of miles for which Uber and Lyft would charge the same amount for the ride.
Let the charge of Uber and Lyft be represented by the variables C1 and C2. We can write the equations given below.
C1 = 20 + 2m
C2 = 15 + 4m
We need the charge for both companies to be equal.
C1 = C2
20 + 2m = 15 + 4m
Hence, the required equation is 20 + 2m = 15 + 4m. Now we will solve this equation to find the number of miles.
2m = 5
m = 2.5
Hence, the number of miles for which Uber and Lyft would charge the same amount for the ride is 2.5 miles.
