Answer:
340 miles
Step-by-step explanation:
From definition of speed, it's distance traveled per unit time
Speed=Distance/time
Making distance the subject
Distance=Speed* time
Substituting speed of 85 miles per hour and time of 4 hours
Distance=85*4=340 miles
Therefore, if the train maintains the same speed, the distance between Sue's house and Kentucky is approximately 340 miles
Follow these rules:
Multiply and divide before adding and subtracting.
(1/4)(1/4) = 1/16, so now we have 1/16 - 1/4 ÷ 1/4 ÷ 1/4 ÷ 1/4
1/4 ÷ 1/4 = 1, so now we have 1/16 - 1 ÷ 1/4 ÷ 1/4
1 ÷ 1/4 = 4, so now we have 1/16 - 4 ÷ 1/4
4 ÷ 1/4 = 16, so now we have 1/16 - 16
1 - 256
and this simplifies to -15 15/16, or ------------
16
You would have to put 21.3 on top and 1.9 under it. then you would have to borrow the number. the answer would be 19.4
