After being kidnapped/on a trip to Canada, little Jimmy was able to see the speedometer of the kidnapper’ s car, and carefully noted down the speeds every tenth of an hour (six minutes). (Since they are in Canada,the speeds are in km/ hr). Jimmy was able to communicate these speeds to his friend Juan Via text message, and Juan wants to ﬁgure out how far away Jimmy is from Where they grabbed him. omework 4 timet 0|.1f.2|.3 .4 .5l.6 .7|.8l.9|1 speedv(t) 30|60|81l93 94 Using the midpoint rule, estimate the total distance (in km) that Jimmy was taken in the one 1 hour, that is, estimate the integral / 11(15) dt. ‘ 0 Under the assumption that —10 S v”(t) S 10, also determine the maximum error in your estimate. ﬂ : AX 3‘ J—vo : i n )0 = .1015 some} +£25.15 +8it+a5+55+16 +56%) M10 Mm: 60.5 WWI distance Mayan/11L Error; KC”) my) _ ,IQ L aw MIG) WM 9‘10 K, 5V l Maximum error zgfo‘, 2.
