Question

You are comparing the range of electric cars. All values must be given in feet using scientific notation.

Ford’s Focus Electric boasts a range of 76 miles on a full charge. The Kia Soul EV claims to have a range of 491,040 feet.
a. Rewrite the range of each car in feet using scientific notation and tell which car has the greater range (remember that 5,280 feet = 1 mile).

Answer 1

At 4.91e+05 feet versus 4.01e+05 feet, Kia Soul EV's range outpaces Focus Electric in scientific feet.

Here's the solution:

1. Convert miles to feet:

Ford Focus Electric: 76 miles * 5,280 feet/mile = 4.01e+05 feet (4.01 x feet)

Kia Soul EV: 491,040 feet (already in feet)

2. Compare ranges:

Kia Soul EV has a larger range (4.91e+05 feet) compared to Ford Focus Electric (4.01e+05 feet).

Therefore:

Ford Focus Electric range in scientific notation: 4.01e
`10^5` +05 ft

Kia Soul EV range in scientific notation: 4.91e+05 ft

Kia Soul EV has the greater range.
