Add 180 and 100 Subtract 180 and 100 Multiply 180 and 100 Use Pythagorean Theorem start 180 ☻ 100 ? ☺ To find how many miles apart the destinations ☻,☺ will be... Use Pythagorean Theorem Click OK start 180 ☻ 100 ? ☺ Pythagorean Theorem Use this formula: 1002+b2=1802 a2+1802=1002 1002+1802=c2 start 180 ☻ 100 ? ☺ (to the nearest mile) Pythagorean Theorem Use this formula: c = 1002+1802=c2 miles start 180 ☻ 100 206 ☺ Pythagorean Theorem Use this formula: c = 1002+1802=c2 206 miles ☻ B 206 ☺ A Half the distance of the 206 mile trip is: miles ☻ B 206 ☺ A How long will it take Truck C to travel 103 miles at 40mph? Use distance = rate*time 2.575 hours .388 hours 4120 hours Distance left to travel after ½ the trip: Total distance: 206 miles 103 miles (to nearest thousandth) Time left to travel after 2.575 hours at 40 mph Total travel time: 4 hours hours Distance left to travel after ½ the trip: You need to travel 103 miles in 1.425 hours. How fast would you need to travel (use distance = r*t)? 103 miles mph (to nearest tenth) Time left to travel after 2.575 hours at 40 mph 1.425 hours Trux The End |
