Post a and post b are 120 meters apart. post b and post c are 300 meters apart. ben cycled from post a to post b in 15 seconds. then he cycled from post b to post c in 55 seconds. find ben's average speed for the distance from post a to post c.

The formula for Velocity(speed) is delta x/ delta t or a change in distance(magnitude) over a change in time. The formula goes as follows X^2 -X^1 / T^2-T^1 so 300-120/55-15 --> 180/40 --> 4.5 m/s(avg. speed).

4.5

Step-by-step explanation:

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!

there is no graph so i cant sorry
