Sasha can run at an average speed of 934 9 3 4 min/mi. She runs at this speed for 6814 68 1 4 min. How many miles does Sasha run

lutik1710 [3]

I don't know what the spaces are meant for but I think that means 934 and 6814 only. Another point is, speed should be expressed in units of distance over time. So that would be miles/min.

So, distance could be calculated by multiplying speed and time.

d = 934 mi/min * 6814 min
d = 6,364,276 miles
