d=r*t

212.5=r*2.5

r=212.5/2.5

r=85

You must travel 85 mph to cover 212.5 miles in 2.5 hours.

212.5=r*2.5

r=212.5/2.5

r=85

You must travel 85 mph to cover 212.5 miles in 2.5 hours.

13[62 ÷ (52 – 42) + 9]

= 13[62 ÷ 10 + 9]

= 13[6.2 + 9]

= 13(15.2)

= 197.6 = 197 3/5

= 13[62 ÷ 10 + 9]

= 13[6.2 + 9]

= 13(15.2)

= 197.6 = 197 3/5
