Answer 1

Answer:

Her average speed was 48..88 mph

Step-by-step explanation:

Use a rule of 3 to find the time she traveled at 60 mph:

60 miles ----------1 hour

40 miles ---------- x

60x = 40

x = 40/60 = 0.67 hours

She traveled 40+50= 90 miles

During 1.25+0.67= 1.92 hours

90/1.92 = 48.88 mph
